Throttle Body Help!

[Smeckel]

I just got my new FMS throttle body that I bought off of ebay. THe seller said it was a 65mm TB so I bought it. Was just wondering if there is any way to tell if its a 65mm or a stocker. I only ask because they have all the same stickers with the same #'s, and I would ahve thought they would be labelled differently. Anyone have any info?

Thanks,
STeve

Hold the new up to the old a 65mm would be noticably bigger then the stock one.My 70mm is way bigger then stock.If they are close that you can't tell measure the distance from side to side of the opening of each.

I tried looking at them but couldn't really see a difference. So I just threw it on anyway and can definetly feel a difference. Thanks anyway guys. One more thing, the spring on top dropped down the side of the engine and I can't find it anywhere. Took it for a drive and didn't notice anything negative, had awesome throttle response though. I won't hurt anything by not getting a new one for a few days, will I?
